APPARATUS FOR THE FILTRATION OF GASES.

SPECIFICATION forming part of Letters Patent No. 758,222, dated ApriI 26, 1904.

Application iiled October 17,1902.' Serial No. 127,707.. (No model.)

To @ZZ whom t may concern,.-

Be it known that I, GEORGE CAMERON STONE, acitizen of the United States, residing at New York, county of New York, State of New York, have invented certain new and usei ful Improvements in Apparatus for the Filtrarality of relatively thin layers, each located within a separate subdivision of the main receptacle, each of said subdivisions or compartrnents .having its individual liquid-discharge and the several subdivisions being independently removable, so that their relative positions may be shifted, if desired, as hereinafter more fully set forth.

In the accompanying drawingIhave shown a central vertical section of a preferred form of apparatus embodying my invention. i

Referring to the drawings, A indicates the upper or hood portion of the apparatus, provided with the gas-inlet opening a, and Bindicates a similar section at the bottom of the apparatus, provided with the gas-discharge apertures Intermediate of the sections A and B are the separate subdivisions or compartments hereinbefore referred to, which in the presentA instance are three in number, though it will be understood that, if desired, their number may be increased to the extent necessary for any particular use. Each of the said subdivisions or compartments consists of a flanged chamber c and a superjacent anged chamber d. These chambers @and d are adapted to be interposed between the two sections A Band may conveniently be held in place therein by means ofthe removable pins e, so that, for instance,y the lower compartment may be removed at any suitable stage of the operation, the two upper compartments lowered, and a new or substitute compartment inserted in the place of the uppermost vone of the series,

ing t', so as to'defiect the gas and also to prevent the liquid condensate from one compartment passing into the compartment below.

Each subdivision of the apparatus is provided,Y

as shown, with its individual trap-discharge r.

The operation of the invention will be apparent. The furnace-gases to be treated enter the apparatus through the inlet-opening c and pass down successively through the relatively thin layers of material m and finally issue at the exit-opening On their passing downward the gases are deflected by the plates s and, entering the spaces beneath the respective screens, commlngle therein before pass-v ing onward through the openings z. The.

structure is therefore adapted to more uniformly filterV the body of gas passing through it than would be the case if these diaphragme and deflecting-plates were absent. The condensible constituents present in the gases run down the inclined sides of the diaphragme and are separately collected from each compart` ment without passing onward to its neighbor in the series. This I find to be particularly desirable, for the reason that the material upon the screens, subdivided as it is into relatively small layers, is kept at a high degree of eiciency by the immediate carrying Off from each layer of the condensates that would oth erwise pass on to the layer beneath it.

While in many instances I prefer to make -the parts c and 0l of each compartment'separate, as illustrated in the drawings, yetin other instances they may constitute a single integral structure.

Having thus described my invention, what I claim is- 1. In apparatus of the kind described, a receptacle having a gas-inlet and a gas-outlet,

' said receptacle being' subdivided into a series of communicating compartments or subdivisions, each of said compartments comprising a diaphragm, a screen above said diaphragm and loose material upon the several screens, the space between each diaphragm and screen constituting a liquid-reservoir, said space being provided with an outlet-pipe for said liquid, substantially as described.

2. In apparatus of the kind described, a receptacle having a gas-inlet and a gas-outlet, said receptacle being subdivided into a series of compartments or subdivisions, each of said compartments comprising a conical diaph ragm havinga central opening, a screen above said diaphragm and loose material upon the several screens, the space between each diaphragm and screen constituting a liquid-reservoi r, said space being provided with an outlet-pipe, substantially as described.

3. In apparatus of the kind described, a receptacle having a gas-inlet and a gas-outlet,

said receptacle being subdivided into a series of compartments or subdivisions, each of said compartments comprising a conical diaphragm having a central opening, a screen above said stantially as described.

4. In apparatus of the kind described, a receptacle having a gas-inlet and a gas-outlet, and a series of intermediate subdivisions or compartments, each compartment consisting of a flanged lower section having a perforated diaphragm and a liquid-tap and a 'flanged upper section having a screen and loose material resting upon the screen, substantially as described.

In testimony whereof IaiX my signature in presence of tWo Witnesses.
